I'm looking for a good rear rack for my bike - one that can handle a trunk bag and some panniers. It will be for commuting only (no touring). My bike has bosses for a rack near the dropouts, but not near the seat tube on the seatstays. I bought a "One Fits All" Topeak Explorer rack only to find out that it needs the seatstay bosses, so it will be going back to the store. Topeak recommended getting a rack that mounts to the seatpost, but I'd like to avoid those if possible. Do you have any recommendations?
